Status: RESOLVED DUPLICATE of bug 1161767

(Firefox :: Tabbed Browser, defect)

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:44.0) Gecko/20100101 Firefox/44.0
Build ID: 20160123151951

Steps to reproduce:

I have two windows open with multiple tabs. When I drag a tab to move it from one window into another and don't place it as the first tab, but in between two other tabs, I see a blue somewhat highlighted separator bar inline with the other tabs. 


Actual results:

This bar doesn't disappear but floats over (or sometimes inbetween) two tabs. In disappears if I refresh Firefox or reorder other tabs. This happened in the last version as well. I was hoping it'd go away by now. 


Expected results:

The blue bar that was letting me know in what order my tabs would appear or where I wanted to place my tabs should have disappeared after the new tab was placed in the window bar. It doesn't.
